    This is a great flash cards game, and I’ve only had this for
    about 10 minutes! I suppose that all 390 mathematical prob-lems where two of the three numbers have just single digits,
    can be viewed (with the paid application, of course!) at the
    same time!

    That means the following can be shown: 0 + 0 to 9 + 9 for addition, 0 – 0 to 18 – 9 for subtraction, 0 x 0 to 9 x 9 for multiplication, and 0 / 1 to 81 / 9 for division. Of course, there are thousands more to solve in just seconds!
